Compact Multifunctional Mass Flow Meters/Controllers for Gases

Redefine your mass flow control

Bronkhorst’s new FLEXI-FLOW combines the advantages of a unique through-chip-sensor with proven by-pass technology. The compact thermal mass flow meters and controllers are 35% smaller than traditional instruments, the smallest on the market for flow ranges up to 20 ln/min. Due to the new sensor technique, the instruments feature very stable flow control, but also very fast control, with settling times smaller than 150 ms.

FLEXI-FLOW instruments have integrated temperature and pressure sensors and an on-board gas database for highest accuracy, even at varying process conditions. With this new technology, the instruments are adaptable to many applications through their wide dynamic flow ranges (up to 1:1000). The temperature and pressure signals may provide the user with information about the actual process conditions. So in fact, FLEXI-FLOW is more than just a flow meter or controller; it’s a multi-parameter measurement/control device.

For easy setup and monitoring of the instruments and your process, Bronkhorst introduces a USB-C port, optional Bluetooth communication, and NAMUR status indication by means of coloured LEDs and digital output parameters. FLEXI-FLOW is available in 2 pre-configured models, as a built-to-order version, or as a customised, multi-channel solution, each including free and easy software tools for configuration, and for diagnostics and predictive maintenance.
